Review

Does The INKEY List Rosehip Nourishing Night Oil work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using The INKEY List Rosehip Nourishing Night Oil:

Strong occlusive moisturizing. This exceptionally occlusive moisturizer, ideal for dry and very dry skin, has a moderate moisturizing rating of 5.0 out of 10, impaired by the absence of humectants.

Moisturizer with the right occlusivity for very dry skin, ideally to be paired with a humectant-rich product

According to CreamScan analysis, The INKEY List Rosehip Nourishing Night Oil is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely occlusive. It has zero Humectancy (we didn't find any humectant ingredients on the ingredient list) and a maximum Occlusivity of 10 out of 10, entirely due to the high content of Rosa Canina Fruit Oil (est. ≈100%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of The INKEY List Rosehip Nourishing Night Oil suggests a rich, thick texture, making it perfectly suited for dry skin.

However, it contains no humectants, and people with dry skin would definitely benefit from adding water-binding humectants to their moisturizing routine for effective dual-action moisturizing. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

According to studies, hovewer, even 10% petrolatum can achieve almost the same mosturizing effect. The occlusive properties of petrolatum are at least twice as superior as other occlusive ingredients. This is why, in order to match the moisturizing efficacy of 10% petrolatum, a product needs to contain at least 20% of other occlusives. Our benchmark for maximum Occlusivity is 20 (and the petrolatum score is always doubled). The most occlusive product possible is 100% petrolatum (hello Vaseline Jelly).
